Tips for Repairing Faulty Batteries

Balancing the internal resistance of battery cells can solve 90% of battery failures. Be sure to follow the operating procedures and use the equipment provided by CMB to connect to the lifepo4 battery for maintenance.
Of course, sending the battery to your nearest CMB repair station is a reliable choice.

parallel and series connection of battery

Protecting the BMS in Parallel Connection

When the different voltages lifepo4 batteries are connected in series, the battery with high voltage will charge the battery with low voltage, and this charging current can destroy the BMS of the battery in only 0.1 seconds (the instantaneous current is very large), so CMB LiFePo4 battery will be equipped with Connecting wires with resistors to ensure the safety of series and parallel battery connection, so that your battery can be used in an RV, and a battery can be removed for portable use as a POWER BANK.

12 volt trolling motor battery

Trolling Motor:

CMB 12V 200Ah lithium iron phosphate battery will become the most reliable partner for your trolling motor, referring to the recommendation:

  • 30 to 55 pounds–12V 100Ah lifepo4 battery
